> Hmm, I don't think this is true. You just need to enable `system()` in configuration Well... Yes and no... system() requires NSH, which is part of the apps package. So, technically, the NuttX kernel does not support it directly. In my case, there is no NSH, so os.execute had to be removed. But

Re: Undefined reference to longjmp/setjmp

Regarding Lua. I have been using Lua in MCU environment for many years now. This is the first time to use it along with NuttX. I am using Lua 5.2.4, for which I have ported the LTR patch, as described here: http://www.eluaproject.net/doc/v0.9/en_arch_ltr.html The way I am using it, is to enable

Re: Undefined reference to longjmp/setjmp

It would be great to put NuttX special build files to apps/interpreters folder after you finish the port, so other people can benefit from your work and improve it in the future. For the code change, I would suggest that: 1. If the api called by 3rd party is very common in other Unix variants but N

Re: Undefined reference to longjmp/setjmp

Since setjmp and longjmp need be called from userspace, the location is moved to: libs/libc/machine/arch Here is the related issue and PR: https://github.com/apache/incubator-nuttx/issues/2478 https://github.com/apache/incubator-nuttx/pull/3315 On Thu, Jun 10, 2021 at 2:51 AM David S. Alessio wr

Re: Undefined reference to longjmp/setjmp

Lua has been ported to NuttX several times.   If you Google for "lua+NuttX" you find lots of hits, many from https://nuttx.yahoogroups.narkive.com. This is from 2018:  https://github.com/tokoro10g/lua-nuttx We really ought to talk to the Lua team and see if we can upstream the changes.  Unsup

Re: Undefined reference to longjmp/setjmp

There is also a configuration option that must be set to use the setjmp in NuttX.  It is in the top-level Kconfig as I recall. You don't get a compilation error so you are probably including the toolchain's setjmp.h.  So most likely you have -nostdlib or something like that on the command line

Re: Undefined reference to longjmp/setjmp

Also, if you need/want help with getting Lua to run on NuttX, let me know. I had Lua 5.1.4 on NuttX (5 maybe it was) a long time ago. I believe I submitted a patch to add it, but I can’t find it now. The addition of Lua to NuttX was in the form of a subdirectory in apps containing only a Make

Re: Undefined reference to longjmp/setjmp

Hello, Foti,I wrote setjmp/longjmp for armv7-m some time ago.  The code should be in file: arch/arm/src/armv7-m/gnu/up_setjmp.SIf not, it’s attached here.Cheers,-david up_setjmp.S.gz Description: GNU Zip compressed data On Jun 9, 2021, at 11:10 AM, Fotis Panagiotopoulos wrote

Undefined reference to longjmp/setjmp

Hi everyone! I just started adding Lua to my NuttX-based project, but I have some problems with it. I am getting undefined references to longjmp/setjmp. I am using an STM32F4 and GCC: arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 9-2019-q4-major) 9.2.1 20191025 (release) [ARM/arm-9-bra
